DRUTI_VT20H
(PITOT TUBE)

The DRUTI_VT20H Airspeed Sensor, indigenously designed by VTOL AVIATION INDIA, is a compact and multifunctional tool tailored to enhance UAV performance. This sensor integrates an airspeed sensor, temperature and humidity sensors, an ARM M4 processor, and a dual temperature control system, all within a single unit. It features adaptive Flex Heater technology for precise data collection in varying weather conditions, and employs SHT45 and MS5525DSO sensors for unparalleled accuracy. Its rainproof design includes effective moisture management to ensure reliability under adverse conditions. Compatible with DroneCAN Protocol and APM/PX4 Firmware, the DRUTI_VT20H offers seamless integration with autopilot boards, making it a vital asset for advanced UAV operations.

FEATURES

  • It integrates a pitot tube, airspeed sensor, temperature and humidity sensor, ARM M4 processor, and dual temperature control system into one structure.  
  • The pitot tube integrates a heating system which uses Flex Heater, that automatically heats according to the ambient temperature and humidity, avoiding data errors caused by pitot tubes freezing or rain blocking, and greatly improving the reliability of UAV operations.
  • Dual Temperature Control System: It uses two sensors SHT45 and MS5525DSO to calculate the temperature.
  • It provides us the Rainproof Structure as it has a drainage hole and heating feature to remove the moisture. 
  • DroneCAN Protocol Support APM/PX4 Firmware, Plug and play system with Autopilot Boards using CAN protocol.
